![]() Nonetheless it’s important to recognize that Docker carries unique risks and they’ll vary depending on your use of the technology. We’re not saying the mere presence of Docker is a security risk, as that’s not the case either. A mistake that’s made too often is to assume Docker’s secured out-of-the-box. Security Is Top Priorityĭocker can increase your stack’s security but it takes work to properly harden your installation. ![]() Hence Docker tends to add less value to compiled language workflows than for interpreted languages where the correct interpreter version can be baked into an image. ![]() Developers are used to installing the IDE and letting it configure their environment. However this tends to end up adding more complexity in disciplines which are driven by IDEs like Android Studio, Visual Studio, and Xcode. As an example, you can create a Docker image that includes Java and the Android Platform Tools to save new developers from having to add these packages to their machines. You could still benefit from Docker in these situations by using it to package the toolchain, rather than the final output. ![]() This kind of software development tends to produce artifacts that either can’t be run in containers or won’t be commonly containerized by users. A common example could be a PHP web application running behind an NGINX web server: there are multiple components including a background server that you want to start from a single command.ĭocker adds less value when you’re creating tools for local use such as desktop programs and mobile apps. Developing Local Tools and Appsĭocker makes the most sense when you’re building long-lived services that have dependencies you don’t want to install in each environment. This is a departure from VMs and OS package installation where you can safely store data in any directory without worrying about how you’ll manage it later on. Data inspections are best performed by getting a shell to the container and enumerating the volume’s content from within.ĭocker requires you to think about storage and choose your own persistence strategy. You need to use Docker commands to interact with your volumes. The data stored within volumes can be tricky to manage and maintain. ![]()
